摘要
选择静态多路径分配方法用于城际轨道交通分配预测。根据有效路径的定义及判定,结合路段路权及节点路权的最短路算法,分别给出路段综合路权及节点综合路权计算模型。以珠江三角洲城际轨道规划线网为例,结合综合交通线网及客流特点,标定综合路权模型,得到珠江三角洲轨道网交通拓扑图,由修正后的最短路算法得出有效路径,运用静态多路径分配方法,实现网络客流分配预测。
This paper selects static multiple route method to be applied in forecasting the distribution of inter-city rail transit. According to the definition and determination of effective route, this paper provides models of synthetical impedances of paths and nodes respectively with consideration of the shortest path algorithm for path impedances and node impedances. Taking the inter-city rail transit planning network of Pearl River delta area for example, the paper calibrates the synthetical impedance model by combining with comprehensive transit network and characteristics of passenger flow, and achieves the topological graph of inter-city rail transit network of Pear River delta. Then the paper achieves the effective paths by using the improved shortest path algorithm, and the forecast of passenger flow distribution is realized by the static multiple route method.
